SPECIFICATION forming part of Letters Patent No. 312,066, dated February10, 1885.

Application filed November 4, 1884. (N model.)

To aZZ whom it may concern.-

Be it known that I, HARRY L. BALSON, of

' De Soto, in the county of Jefferson and State tion taken on line 3 3,Fig. 2. Fig. 4.is a vertical section taken on line 4 4, Fig. 2. Fig. 5is a vertical section taken on the same line as Fig. 4, but showing theparts in different positions. Fig. 6 is a horizontal section taken online 6 6, Fig. 4, and Fig. 7 is a similar view taken on line 7 7, Fig.5.

My invention relates to an improved machine for making bricks; and itconsists in features of novelty hereinafter fully described, and pointedout in the claims.

Referring to the drawings, A represents the frame of the machine, havinga table, A, in which is located the mold or molds A".

B represents an upper and Q a lower plungen D represents the main drive-shaft, journalled in boxes D, and operated by a cog wheel, D thereonengaged by a pinion, D, on a counter-shaft, D, having a pulley, D. Thecounter-shaft is journaled in boxes D secured to suitable supports, andit preferably has a pinion, D, on each end to engage the cog-wheels onthe main shaft-one on each end. The main shaft may, however, be drivenby any other suitable means. The upper plunger is connected by a link,I, to a crank, J, on a rock-shaft, J, journaled in the upper part of theframe. On the outer ends of the rock-shaft are cranks L, connectedbylinks L to sliding blocks L held to the sides of the frame A by stripsA, or by other suitable means. On the lower ends of the blocks arefriction-rollers L, that bear against cams M on the main shaft D. i Asthe shaft turns the blocks are raised from the position shown in Fig. 3to the position shown in Fig. 1, which causes the plunger B to be forcedfrom the position shown in Fig. 5 to the positionshown in Fig. 4, and asthe shaft continues to turn the cams M leave the blocks, which fall,causing the plunger to move back to its upper position. As the upperplunger is lowered the lower plunger is raised by a cam, N, on the mainshaft, and thus the bricks are pressed between them. The pressingmovement of the lower plunger is caused by the part or face N of thecam, so that when the parts are in the position shown in Fig. 4 thepressing is done, and just at this point the upper plunger commences torecede or rise, and the lower plunger is made to follow it, to eject thebricks, by the part or face N 2 of the cam, and then when the cam leavesthe plunger it falls to its lower position; but the plunger is held inits upper position a short time by the part or face N of the cam. Thisis done to give the charger time to shove the brick from over the mold.

0 represents the charger sliding on the table A, to the rear end ofwhich is connected the upper end of a lever, P, fulcrumed at P to theframe A. The lower end of the lever is connected by a link, P to an arm,T, on a rock-shaft, T, to which is also secured two short levers, U andV. On the main shaft is a disk, \V, with a pin, W, on each side, one ofwhich comes against the lever U to raise it, as shown by the arrowin'Fig. 4, which advances the charger to the position shown in Fig. 5.As the shaft continues to revolve the other pin comes against the upperedge of thelever V, and by depressing it'tnrns the rockshaft back,causing the charger to recede. The under edge of the lever U is soshaped that the pin, coming in contact with it, will cause it to beraised. The plunger 0 has a frictionroller, 0, to receive the cam N. Theframe has flanges A to guide the plungers and hold them in place.

X represents a hopper located so as to be over the charger when it is inits normal position.

I claim as my invention-- 1. In a brick -machine, the mold A and upperplunger, B, in combination with the main shaft D, cam M, carriedthereby, sliding block L upon the lower end of which said 100 camimpinges, rock-shaft J, having cranks L W, secured to said shaft, andhaving pins W and J, links L and I, connecting said cranks projectingfrom opposite sides, the rock-shaft with the sliding block L 'andplunger B, re- '1, having arms U and V, against the under spectively,the lower plunger, 0, and the cam and upper faces of which said pinsengage, I 5 5 N, arranged on said shaft D in such position 1respectively, the charger O, and levers conrelatively to the cam M as tocommence its ac- I necting said charger with the rock-shaft T, as

t-ion immediately before the action of the latdescribed. ter ceases, asand for the purpose set forth.

2. In combination, the mold, the plungers 10 B C, the main shaft D,actuating the said plungers, substantially as described, the disk HARRYL. BALSON. In presence of- GEo. H. KNIGHT,
